Title: Improvements in or relating to engine-starting gas turbine systems
Inventor: OLDFIELD THOMAS ALFRED
IPC: F02C6/06
Filed: 1966-11-02
Abstract: 1,201,767. Gas turbine engines. PLESSEY CO. Ltd. Oct.27, 1967 [Nov.2, 1966], No.49234/66. Heading F1G. In an engine-starting gas turbine system of the kind comprising a free turbine 10, Fig.2, for driving the starter output shaft and a speedcontrolled gas generator feeding a combustion chamber 5 for the supply of combustion gas to both the turbine 1 of the gas generator and the free turbine, an accessory drive shaft 19 is driven by one of the turbines, and an overrunning clutch 21a couples the free turbine with the gas generator when the speed of the free turbine tends to exceed a predetermined ratio to that of the gas generator, this ratio being higher than the ratio corresponding to the speed at which the engine becomes self-sustaining. The free turbine 10 may be coupled by reduction gearing and an overrunning clutch to an engine to be started. Alternatively, as described in Specification 1,186, 375, it drives a compressor 23 which feeds compressed air via a non-return valve 26 to either of two starter turbines 28, 29 associated with two aircraft engines, the selection being made by valves 30, 31. After completion of the starting operation, the free turbine remains in use to drive auxiliaries through the shaft 19; being relieved of the starting load, it speeds up until it reaches the speed of the turbine 1, whereupon it is coupled to the latter by the overrunning clutch 21a and thereafter assists the driving of the gas generator, the speed of both turbines then being controlled by the governor 16 of the gas generator. The power absorbed by the idling compressor 23 may be reduced by adjusting a throttle 32 to restrict or exclude the entry of air through the inlet 24. When compressed air is available from an external source it can be fed through a non-return valve 6 to start the engines. Bleed air may be tapped from the compressor 23 or the compressor 3 of the gas generator. The overrunning clutch may be protected from high temperatures by being incorporated in a layshaft arranged outside the housing of the unit. The end of the layshaft which is permanently connected to the gas generator may be used to drive, e. g., a fuel pump.
